= Semi-infinite Eady model
A uniformly stratified <quasi-geostrophic approximation> fluid with constant vertical shear occupies $z>0$, has a flat rigid lower wall, and has decaying perturbations aloft. On an <f-plane>, the basic interior <potential vorticity> is constant. Its smooth edge-wave modes have zero interior anomaly and propagate along the lower-boundary <buoyancy> gradient. The absence of an upper wall removes the pair of interacting edge waves that makes the finite-depth <Eady model> unstable.
